\ 1 Claim. (CL 299-96) This invention relates`\ to improvements in Fig. 6 is a sectional detail of a spray nozzle dispensing devices and has particular reference that may be employed in connection with the to a device that may be appliedY to any container device. of uids or liquids for dispensing the said fluids or Referring now more particularly to the drawliquids from the container in either an atomized ing and especially to Figures 1 and 2 thereof, spray form or in a fine stream which spray or the improved spraying device consists generally stream is ejected from the container by a slight of a bottle or like capping member I0, which in pressure upon a ilexible bulb associated with the the instance shown embodies the usual screw device. cap member Il of a small liquid container I2,

In the accompanying drawing forming a part Tn Figure 3 I have shOWh e Slightly modled of this specification and in which like numerals form 0f the device in Which is included a ballare employed to designate like parts throughcheck valve 2li enclosed in a tube 2l, inserted in out the same, the member le. In this arrangement the only 40 Flg l ls an elevation Showing a uuid or llquld difference is that the ball-check valve which container such as a small bottle or vial with my elOSeS When the element ifi is depressed iS Opened improved dispensing device in place thereon, when said element is released, thus allowing air Fig. 2 is a greatly enlarged sectional detail of t0 ente! the Chamber 22 Providing fluid pressure the capping device illustrating the means of atfel' the next eieetien 0f liquid 01' ilu-id through 45 tachment to the container and further illustratthe nOZZle 0f the device. ing the liquid ejecting means of the device, In Figure 5 u Somewhat different form is shown Fig. 3 is an enlarged sectional view of a liquid and includest-A flexible or soft rubber ejector spraying device of a slightly modied form in il positioned upon a hard rubber or like member so which is included an sir iniet beu-check valve, 23 which member. between its partition 24 and 50 Fig. 4 is an enlarged sectional view of the ballthe ejector forms a chamber 25, the partition 24 check valve shown in Fig. 3, having a gasket 26 arranged thereunder to cause Fig. 5 is a sectional detail of another modia tight ilt between the cap and container and ed form of the device in which a slightly diffurther embodying a glass ejector tube 21 of taferent arrangement of parts is illustrated, and pered form in the lower end of which is arranged 65 a ball valve 28. An ejector nozzle 2l, in which-a ball-check 30 is included, completes this modiiled form which functions as follows:

When pressure is applied' to the member I4 the ball check 30 is unseated and the check 28 is seated in the tapered tube 21, however, when the element I4 is released the vacuum caused by this action causes the unseating of the ball check 28 and the drawing of a measured amountl of liquid or fluid to and through the tube 21, and into the chamber 25; and when pressure is again applied to the element I4 the charge is ejected throug the ball-check 30 and the nozzle 29.

Referring to Fig.6 it will be noted that I have ,v

shown a particular form of ejector nozzle which may be employed in connection with my invention and which consists of an ejector tube 3| havl ing a closure valve 32 arranged therein, and

which valve may be employed to close the discharge tube especially for sealing the contents of the container for storage or shipping purposes. I have found from experience that the present device is highly serviceable as an eye dropper.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material. size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, I claim:-

In a device of the class described, a liquid container, a screw cap member therefor, a resilient washer tted in the upper end of said screw cap and having a perforation formed therein, an ejector tube extending through the perforation in said washer and having a spray nozzle formed at its outwardly bent end, a resilient ejector element tted over the upper edge of said screw cap and forming a chamber above said washer, and a ball check valve fitted through one side of said resilient element, whereby when pressure is applied to said ejector element, fluid is forced from the container through said ejector tube. thereby simultaneously closing said check valve, and when said ejector element is released, said check valve opens, allowing a charge of air to enter the chamber for the next ejecting operation.
